Abstract

A simple optical fiber temperature sensor is under development. The expected temperature range to be measured by the sensor is from minus 50 degrees Celsius to over 1000 degrees Celsius, and the measurement accuracy is 1 degree Celsius. The sensor is robust against harsh environments. It is immune to source fluctuations, surface deterioration of the optical element inside the sensor head, and coupling inconsistency [sensor to electro-optics (EO) board]. The sensor is constructed so that calibration is done automatically upon installation. The sensor uses a high-temperature fiber and a high-temperature metal, and its operation is based on a simple optical interferometer. The source for the sensor is a wideband (white light) source. Data processing software is needed to operate the sensor. The frequency response is 10 Hz or faster. A breadboard sensor made of stainless steel and a silica fiber was built and tested to temperatures up to 500 degrees Celsius. The results show the feasibility of the proposed concept.
